Open transport map — Routable OpenStreetMap

This paper introduces Open Transport Map (OTM). The OTM is a web based map, depicting the road network of the Europe. The road network is derived from open source OpenStreetMap (OSM) but the data is stored in the Infrastructure for Spatial Information in the European Community (INSPIRE) Transport Network compatible data scheme. OTM is (contrariwise the OSM) topologically clean and routable data source, suitable for network analyses. A calculation of time and place related traffic volumes is one of analysis possible to perform on the base of such a data. The calculation of traffic volumes combines demographic data about the population and a road network vector data to create an enriched traffic model. This model can simulate traffic volume changes in the network through the time. The OTM is developed within the European projects OpenTransportNet, SDI4Apps and Foodie and it is freely available (under the ODbL license) for user's further use.
